When to use
- Adult early-warning scoring, with Scale 2 for patients with target saturations of 88-92% (e.g. chronic hypercapnic respiratory failure).
Formula
As NEWS but SpO2 uses Scale 1 or Scale 2, supplemental O2 adds 2, and new-onset Confusion scores 3 in the ACVPU item. Low 0-4, medium 5-6 or any single 3, high >=7.
Pearls and pitfalls
- Use Scale 2 only for patients with a clinically agreed 88-92% target; misapplying it under-scores hypoxaemia.
- New confusion or delirium now scores in the consciousness item.
